Details

Rukovoditel is an open-source project management tool and CRM tool designed to support project managers in complex tasks.

Multiple authenticated SQL injection vulnerabilities exist in the ‘entities/fields’ page of the Rukovoditel Project Management App. These SQL injections occur multiple times in different switch cases (mulitple_edit, export or copy_selected) for two different parameters entities_id and selected_fields. Another SQL injection vulnerability exists in this page for the heading_field_id parameter. An attacker either needs administrator privileges or they could trigger these vulnerabilities through cross-site request forgery.

CVE-2020-13588 - SQL injection in the heading_field_id parameter

The heading_field_id parameter in ‘‘entities/fields’ page is vulnerable to authenticated SQL injection. The following request would trigger the vulnerability:
